ADJUSTABLE WINDOW-SHADE ROLL AND HOLDER THEREFOR.

Specification of Letters Patent.

Application filed January 27, 1909.

Patented Oct. 10, 1911.

Serial No. 474,401.

To all whom it may concern:

Be it known that I, FRANcEsco FERRARA, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Adjustable Window-Shade Rolls and Holders Therefor, of which the following is a specification.

This invention relates to an improved means for supporting the ordinary springactuated window shade roll, consisting of two separate holders, one of said holders being adapted to be attached to the journal pin which is fast to the window shade roll, the other of said holders being adapted to be attached to and detached from the spindle to which the spring which rotates the roll is attached. Each of these holders is adapted to be attached to its respective cord and, preferably, one cord is attached to its holder at a point outside the vertical plane in which the median axial line of said roll is located.

The holders are very small, light and perform every function which is necessary in order that the curtain shall be unrolled from its roll or rolled thereupon, and also said holders render it possible, by means of said cords, to raise and lower the roll, with the curtain thereon, bodily, so that the curtain may be used to cover any desired portion of the upper or lower window sash, or both of said sashes, thus making it possible to open the window at the'top or at the bottom, or both top and bottom, and still have the cur tain cover that portion of the sashes located between the open spaces.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a front elevation of my improved curtain roll and holders therefor, the same being shown suspended on cords and in connect-ion with a window sash and casing. Fig. 2 is an end elevation of the holder in which the journal pin is rotated taken from the left of Fig. 1. Fig. 3 is a sectional elevation taken on line 3-3 of Fig. 2. Fig. 4 is a sectional elevation taken on line 4-4 of Fig. 8. Fig. 5 is an end elevation of the holder in which the spring spindle is mounted, as viewed from the right of Fig. 1. Fig. 6 is a sectional elevation taken on line 66 of Fig. 5. Fig. '1 is a sectional elevation taken on line 77 of Fig. 6. In Figs. 3 and 6 a portion of the window shade roll is shown in connection with the respective holders, the same being broken away to save space in the drawings.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 is a window casing, 11 a window sash, 12 a window shade roll, 13 a window shade fast thereto.

14 is the journal pin holder, 15 the spindle holder, 16 and 17 are cords fastened, respectively, to the journal pin holder and the spindle holder, and extending therefrom upwardly over guides 18 and 19, respectively, thence over a guide 20 fast to the window casing, and from said guide 20 extending downwardly to a suitable hook or bracket 21 to which they may be fastened.

The roll 12 has fastened to its left hand end a journal pin 22 which has a flange 23 thereon.

The holder 14 consists of a preferably cy lindrical casing wall 24 having a back piece 25 with an arm 26 thereon which terminates at its free end in a finger-piece 27. Preferably the back piece 25 and arm 26 are formed in one piece which constitutes a U-shaped arm, the back piece 25 constituting one leg thereof and the arm 26 constituting the other leg thereof. The outer end of the pin 22 is journaled in a substantially cylindrical hole 29 in the arm 26. The back piece 25 is slotted at 28 to receive that portion of the pin 22 between the flange 23 and the roll 12. The slot 28 is made larger at its upper end than at its lower end, in order that the flange 23 upon the pin 22 may pass therethrough and then said pin drop downwardly in the holder until the shank thereof rests in the smaller lower end of said slot 28.

The cord 16 extends through a hole 30 in the cylindrical wall 24 of the holder 14, and this hole 30 is preferably located in the vertical median axialplane of the roll 12, as will be seen in Figs. 2 and 4.

To attach the holder 14 to the journal pin 22, the pin 22 and the flange 28 are pushed through the slot 28, in the larger part thereof, and then drop down into the position shown in Figs. 8 and 4. At this time, the arm 26 is sprung outwardly into the position shown in dotted lines (Fig. 3). After the pin has been dropped into the lower portion of the slot 28, the arm 26 springs into the position shown in full lines (Fig. 3) with the outer end of the pin 22 extending through the hole 29 which forms a journal bearing for said pin.

To remove the holder 14 from the roll 12, the reverse of the operation hereinbefore described is followed, the arm 26 first being sprung outwardly, by means of the fingerpiece 27, from the position shown in full lines (Fig. 3) to that shown in dotted lines, and the roll then disconnected from the holder by moving the pin upwardly in the slot 28 until the flange is in alinement with the enlarged upper end of said slot, when the same can be moved therethrough and the holder 14 thus disconnected from the roll.

The curtain roll 12 is actuated in the usual manner by a spiral spring 31 which is contained within a recess extending longitudinally of the roll 12 and is fastened at one end thereof to the roll and at the'other end thereof to a spindle 32 which extends longitudinally of the roll 12 and beyond the right hand end thereof (Fig. 1); Said spindle is flattened on opposite sides at its outer end at 33, 33 in the usual manner and is provided with longitudinal recesses 34, 34 which are adapted to be engaged by pawls 35, 35 pivoted to the roll 12 and adapted to drop into said recesses 34 and prevent the rotation of the roll relatively to the spindle.

The holder 15 consists, preferably, of a split ring 36 which has an arm 37 extending inwardly therefrom and provided with a slot 38 into which the flattened end of the spindle 32 projects. Said split ring has also two arms 39 and 40 formed on or secured thereto at diametrically opposite points, the arm 39 being provided with a projection or tooth 41 and the arm 40 being provided with a projection or tooth 42, see Fig. 7. These projections 41 and 42 project into the recesses 34 as seen in Fig. 7 and thus prevent the holder from becoming detached from the spindle by movement longitudinally thereon since the recesses 34 are provided with shoullders at their outer ends. The arm 39 is provided with a slot 39 and the arm 40 is provided with a slot 40, see Fig. 7, and through these slots the spindle 32 projects.

The cord 17 is attached to the holder 15 by beingknotted at one end thereof and v passing through a hole 43, said hole being located outside the vertical plane in which the median line of the roll 12 is located. As

shown in Figs. 5 and 7, the curtain being lplane.

To attach the holder 15 to the spindle 32, the opposite sides of the split ring are pressed toward each other, thus moving the projections 41 and 42 away from each other to a sufficient distance to allow the spindle 32 to be inserted therebetween, while the flattened end of said spindle projects into the slot 38 in the arm 37 The sides of the split ring are then released and the resiliency of said split ring causes the projections 41 and 42 to move toward each other and into their respective recesses 34 in the spindle 32. The holder is then locked to the spindle so that it cannot become detached therefrom by moving longitudinally thereof, and said spindle is prevented from rotating relatively to the holder by the fiattened portion which projects into the slot 38 in the arm 37 fast to and forming a portion of said holder.

To remove the holder 15 from the spindle and from the roll, the sides of the split ring are pressed toward each other until the proj ections 41 and 42 pass out of the recesses 34 and the holder 15 is then free to be moved longitudinally of the spindle and thus detached therefrom.

The general operation of the device hereinbefore specifically described is as follows: Havingattached the holders 14 and 15 to the roll, as hereinbefore described, the cords 16 and 17 being attached to the holders 14 and 15, respectively, and carried through the guides shown in Fig- 1, the curtain roll and its shade, together with the holders 14 and 15, are raised by pulling downwardly upon the cords 16 and 17 at the right of the casing 10. Said roll and the parts carried thereon are lowered by releasing the cords 16 and 17 at the right of the window casing 10. When the roll has been raised or lowered to the desired location, the same is held in position by winding the ends of the cords 16 and 17 around the bracket or hook 21. The shade 13 is unrolled from the roll or rolled thereupon in the usual well known manner. If desired, one of the cords 16 or 17 may be released while the other cord is held stationary, and this will result in dropping the window shade roll to a vertical position at one side or the other of the casing, thus removing the roll entirely from in front of the window panes.
